What was a secret society of mathematicians that studied geometric ratios such as the golden ratio?
The secret society of mathematicians often associated with the study of geometric ratios, including the golden ratio, is the Pythagorean Brotherhood. Founded by the ancient Greek philosopher Pythagoras in the 6th century BCE, this group not only explored mathematics but also delved into philosophy, music, and cosmology. They believed that numbers and their relationships were fundamental to understanding the universe, and they maintained a level of secrecy about their teachings and discoveries. The Pythagoreans famously linked mathematical concepts to aesthetics and natural phenomena, particularly through their study of ratios and proportions.
How do you calculate j value for triplet of doublet?
To calculate the j value for a triplet of doublets in NMR spectroscopy, you first need to identify the coupling constants involved. A triplet of doublets arises from a proton that is coupled to two neighboring protons, resulting in two distinct doublets. The j value is determined by measuring the distance between the peaks in the doublets (the separation between the peaks) and the distance between the doublets themselves. Typically, you would report the coupling constants (j values) for the two sets of doublets separately, reflecting the different interactions with each neighboring proton.
What is the application of beta and gamma function in mechanical engineering?
In mechanical engineering, the beta and gamma functions are used in various applications, particularly in the analysis of complex systems and materials. The gamma function, for instance, is instrumental in calculating probabilities and statistical distributions, which can be essential in reliability engineering and quality control. The beta function, on the other hand, often appears in problems involving fluid mechanics and thermodynamics, helping to evaluate integrals related to beam deflections and stress distributions. Together, these functions facilitate the modeling and analysis of physical phenomena, aiding engineers in optimizing designs and predicting system behaviors.
Why dielectric constant has no units?
The dielectric constant, also known as relative permittivity, is a dimensionless quantity that represents the ratio of a material's permittivity to the permittivity of free space (vacuum). Since it is defined as a ratio of two similar quantities (both having units of capacitance per unit length), the units cancel out, resulting in a value without units. This property allows for easier comparisons between different materials' electrical characteristics.
What is the volume of a liquid in science?
In science, the volume of a liquid refers to the amount of space that the liquid occupies. It is typically measured in units such as liters (L), milliliters (mL), or cubic centimeters (cm³). Volume can be determined using various methods, including displacement of water for irregular shapes or using graduated containers for regular shapes. Accurate measurement of liquid volume is crucial in experiments and applications across various scientific fields.
Do relative permittivity and dielectric constant of a medium imply different physical qantities?
Relative permittivity and dielectric constant are often used interchangeably, but they can imply different contexts. Relative permittivity (ε_r) is a dimensionless measure of a material's ability to store electrical energy in an electric field, relative to the vacuum. The term "dielectric constant" traditionally refers to this same quantity, but it can sometimes be used more loosely to describe the material's overall insulating properties. Thus, while they represent similar concepts, the terminology can depend on the specific physical context being discussed.

What is nitrogen's atomic mass?
Millions of tons. !!!!!
Nitrogen forms 79% of the world wide atmosphere.
The total mass of the atmosphere is estimated to be 5.15 x 10^(18) kgs.
[5,150,000,000,000,000,000 kgs].
So 79 % of this mass is 4.0685 x 10^(18) kgs of nitrgoen .
Why is division by zero is undefined or not allowed?
Any non-zero number divided by zero is infinity (positive or negative), but your calculator may give an error. Try it with a very small number such as 0.000001, as you make it smaller the result will become larger. The reason is that for a given number, you can put 0 into it as many times as you want - an infinite amount.
However, this will give us many problems with division. For any other number, division has very useful properties. If we have some unknown number called 'x', and we have an equation that says: x/3 = 5/3, then we can deduce that x=5. Another example: x/4 = 7/4. We can deduce that x=7. But when we allow division by zero, this property is lost: 3/0 = infinity = 4/0, but 3 is not equal to 4. We also lose many other useful properties if we allow division by zero. However, we do almost allow division by zero. This is done by taking what is known as a limit as the divisor, x, tends to zero (we write x→0), and this is an integral part of calculus.
0/0 is a special case of division by zero. Notice that for any non-zero number, let's call it 'y', we get y/y = 1. But we say that 0/0 is undefined, or indeterminate. We can still take limits when something looks like it might be equal to 0/0. For example, the limit of sine(x)/x as x→0. We know that sine(x) = 0 when x=0, but it can be proven that sine(x)/x →1 as x→0. But we can also prove that x2/x → 0 as x→0. So the result is different depending of different situations.
Yes, 3.14 is an approximation of the mathematical constant pi (π), which represents the ratio of a circle's circumference to its diameter. Pi is an irrational number, meaning it cannot be expressed as a simple fraction, and its decimal representation goes on infinitely without repeating. While 3.14 is a commonly used approximation for pi, the actual value of pi is approximately 3.14159.
Often, in mathematical problems, you are asked to find out an unknown value. Towards that end, you are "given" some numbers to assist in that process.
Why is zero factorial equal to one?
n!/n = n!/n | reflexive property
(n)(n-1)(n-2).../n = n!/n | definition of factorial
(n-1)(n-2)... = n!/n | cancelling the common factor of n
(n-1)! = n!/n | definition of factorial
Notice that, in order for n! to be described as (n)(n-1)(n-2)... and proceed to be rewritten as (n-1)! after the n's cancel, the natural number n had to be greater than some natural number for (n-1) to be a factor in the factorial. This means that n must be at least 2, because if n were 1, (n-1) would not have been a factor of the factorial, and the proof would fail unless we assume that n is at least 2. So now you know that this rule cannot prove that 0! is 1 because 1 cannot be substituted into the rule because, as it stands, the rule is only valid for values of 2 or greater. The rule is valid for values of 1 or greater if it is assumed that 0! is 1, but that is what you are trying to prove.

What is the biggest number other than infinity?
This question can not be answered for the following two reasons:
- In the modern real number system, there is no limit to how large a number can be. Whatever number is presented to you, you may add 1 or more to it to make it even bigger than it was originally.
- Infinity is not a number. Infinity is a concept that in the number system there is no definite end to the positive or negative value a number may have.

If you are just looking for a very large number, a 'googol' is the number 1 followed by 100 zeroes, and that is one of the largest numbers that actually has a name.
A centillion (10103) is the largest standard named number.
A googolplex is a 10 to the googol power (a 1 followed by a googol number of zeroes), which is larger yet.
Mathematical exponent numbers such as Skewes number are much larger still.
If aleph null represents the cardinality of the rational numbers, aleph null plus one has the same value. The size of infinity represented by the reals is, however, demonstrably greater than the size of infinity of the counting numbers. We can construct ever larger sizes of infinity. One interesting question is whether or not there are sizes of infinity between aleph null and the power set of aleph null (which represents the cardinality of the reals). It turns out the answer is yes or no, depending on what you want. You can treat the question as an independent axiom of mathematics, much like the parallel postulate in geometry.
How do you evaluate 6n for n 6.23?
